Command "DLookup"

I have problem with the command "DLookup" in Access 2000.
The command takes very long time to run.
Have anybody any solution for this.

This is usually faster than DLookup:
http://easyweb.easynet.co.uk/~trevor.../baslookup.zip

But the underlying problem may remain, depending on what that is, what
you're selecting from, any criteria you're using, what is/is not
indexed, how many records, etc. There are so many variables to determine
the speed at which something will run.

First, DLookup is not a command! A stored query based on the same table or
query with the same criteria will run much faster.

When running "tLookup" the code stop on "inum", do I need any special
DLL-file or something other.

It requires a reference to DAO although there's no "inum" that I know
of, perhaps it stoped in your own code because of a compile error?
(cause by lack of DAO reference)

Sorry!

It should be "ENUM" not "INUM"
I have added reference to DAO, but the program still stop at "ENUM".

Aha, Sorry your version of Access is not as advanced :-)

Just change the block:

Public Enum tLookupReset
tLookupDoNothin g = 0
tLookupRefreshD b = 1
tLookupSetToNot hing = 2
End Enum

to:

Public Const tLookupDoNothin g = 0
Public Const tLookupRefreshD b = 1
Public Const tLookupSetToNot hing = 2

It will still work but you won't get the intellisense combo to choose
those values when you code it although typing "tlookup" then hitting
Ctrl+space will pop them up.

Hi, I'm running into a problem with Access XP (SP2) that's driving me up the wall. It's Error 2001 "You canceled the previous operation". There is no voodoo going on really when I get this message. The following Dlookup field is causing this message. All field data types are correct. DLookup("tDescription", "RelatedTable", "iIntegerField = " & (DLookup("iIntegerField", "TableOne")))

DLookup("", "tblPreliminaryVINs", "=Forms!frmVINODO!SerialNum") is giving me a Type Mismatch error. That's confusing to me and I don't know how to circumvent it. The field in tblPreliminaryVINs is a 17-char text field. Forms!frmVINODO!SerialNum is just an unbound textbox on a form (frmVINODO). I run the DLookup during the textbox's BeforeUpdate event code. Some VIN values I type in there do NOT give rise to the error. Some do. By

I have a problem I just can't figure out. I have a form with a subform, and the recordsource of the subform has criteria based on some unbound fields in the parent form so that data in the parent form affects data in the subform. I've had this type of setup often, but I've run across a couple forms where this has caused an "enter parameter value" pop up for each reference to the parent control in the query when the main form is closed. ...
